Primare A35.8 8 Channel Amplifier

The A35.8 is Primare’s most powerful and flexible multi-channel amplifier, designed to serve the needs of virtually any high-performance multi-channel system through its ability for each pair of channels to be bridged to mono for an incredible level of power delivery and system building options, including 1500 watts of total output in a fully bridged bi-amped stereo configuration.

Key Features

XLR and RCA inputs for each of eight channels of amplification with 150 watts per channel output into 8 ohms, with a maximum output of 1500 watts.

Each pair of output channels can be bridged, allowing the amp to provide power to virtually any multi-channel speaker configuration, either on its own or with an A35.2 stereo amplifier.

For an extraordinarily powerful two-channel bi-amplified system, one fully bridged A35.8 delivers peak power of 4 x 375 watts or 750 watts per pair per channel.

Additional convenience features include auto-sense turn-on from standby and auto standby after an absence of input signal for twenty minutes which can be turned off allowing the A35.8 to remain on indefinitely if preferred.

Primare A35.8

Joint Best Product, Awarded by Both Home Theatre and HiFi Audio Groups

“Designed for both the home theatre audio and hi-fi worlds, Primare’s multichannel 35 Series amplifier deploys eight bridgeable channels of potent, dynamic Hypex Ncore amplification, and then lets the user decide what to do with them. This is a flexible, innovative, and imperious-sounding amplifier, in a stylish, understated chassis typical of the brand.“

Amplifier technology 

The ingenious design of the A35.8 circuit layout provides the most direct delivery and even distribution of power from the power supply to the amp modules tucked into heatsinks that isolate them from any power supply noise. In turn, this innovative construction isolates the input and output stage from any noise the amp modules might produce. Input and output signals are delivered to and from the amp module through an uninterrupted ribbon of circuit board threaded through a channel in the heat sinks for the shortest possible signal path. 

System Configurations 

The bridging capabilities of the A35.8 allow it to be used in a variety of system configurations, with or without the addition of a stereo amplifier, to suit most multi-channel system requirements. A few examples: 

  • 5.1, 7.1 and 5.1.2 channel systems can be powered by a single A35.8 
  • 5.1.4, 7.1.2, 7.1.4 channel systems can be driven by combining an A35.8 with a number of A35.2 stereo amplifiers 
  • 9.1.6 and 13.1 Auro 3D systems can be configured using two A35.8 amplifiers
